strong and you might not be able to control the power
cutter.
If the blade is pinched or stalled in the kickback zone,
the reactive force will push the power cutter up and back
towards the user in a rotating motion causing serious or
even fatal injury. Be alert for potential movement of the
work piece. If the work piece is not properly supported
and shifts as you cut, it might pinch the blade and cause
a kick back.
To cut in pipes
WARNING: If the blade is pinched in the
kickback zone it will cause a severe
kickback.
Special care should be taken when cutting in pipes. If
the pipe is not properly supported and the cut kept open
through out the cutting, the blade might be pinched. Be
especially alert when cutting a pipe with a belled end or
a pipe in a trench that, if not properly supported, may
sag and pinch the blade.
If the pipe is allowed to sag and close the cut, the blade
will be pinched in the kick back zone and a severe kick
back might develop. If the pipe is properly supported the
end of the pipe will move downward, the cut will open
and no pinching will occur.
1. Secure the pipe so it does not move or roll during
cutting.

2. Cut section "I" of the pipe.

3. Ensure that the cut opens to avoid pinching.
4. Move to side II and cut from section I to bottom of
the pipe.
5. Move to side III and cut the remaining part of the
pipe ending at the bottom.
To prevent a kickback
WARNING: Avoid situations where there is
a risk of kickback. Take care when using
your power cutter and make sure that the
blade is never pinched in the kickback zone.
WARNING: Be careful when you put the
blade in an existing cut.
WARNING: Make sure that the work piece
cannot move during a cutting operation.
WARNING: Only you and proper working
technique can eliminate kickback and its
dangers.
